    GFI Hot Tub Problem

    Hello Jim, Sorry it took so long to reply. I was out of town. I am going to disconnect the heater this am and see what happens. In the meantime, the answer to your question is yes. The GFCI pops when I only connect the ground wire.

    GFI Hot Tub Problem

    Thank you, I made a mistake and what I wrote. There is no neutral between the GFCI secondary breaker box and the spa. Just the red, black and ground.

    GFI Hot Tub Problem

    Thank you both very much. The wiring from the GFI breaker to the hot tub was just replaced last week. The existing wiring was corroded. So it was replaced. The spa neutral does go to the breaker and then to the ground bar in the panel in the hot tub. I completely disconnected the new wiring...

    GFI Hot Tub Problem

    My Hot Tub GFI keeps tripping. The first thing I want to do is determine whether the problem is: 1) the hot tub or 2) the wiring to the hot tub. I want to do a simple test where I disconnect the wiring at the hot tub. I would go to the main lugs in the hot tub and remove the wires which are...

    Power outage problems with main pool pump and booster pump.

    Thank you for this tip. I have a question though. My main Pentair Intelliflo resets its clock when the power goes off ( it does not hold time time). How do you deal with that?

    Power outage problems with main pool pump and booster pump.

    Thank you very much. I may be mistaken, but I thought the Intelliconnect cost a few thousand, not a few hundred. But maybe I dont understand. Thanks again!

    Power outage problems with main pool pump and booster pump.

    Hello, I live in an area that frequently has power outages (one or two a month). This creates a problem for me with my pool because I have a main Pentair pool pump (which is controlled by the digital timer built into the pool pump) and a separate booster pump which runs off a mechanical...

    Looking for bearing and seal kit for Pentair LA01N Booster Pump

    How right you were. You said "make sure you can get the motor apart". I could not. Two of the bolts that hold the motor stand onto the motor broke off. They had clearly been overtightened on original assembly. Thanks for your help.

    Looking for bearing and seal kit for Pentair LA01N Booster Pump

    I actually purchased a bearing and seal kit from a guy in Long Island. I purchased the kit before I saw your response. So, I am going to give it a try. I really appreciate your detailed response on "how to". I will let you know. In the meantime, I think my bearings became shot because a power...

    Looking for bearing and seal kit for Pentair LA01N Booster Pump

    Hi, my bearings are shot in my booster pump (Pentair LA01N) and I want to replace them (and any of the seals along the way). Does anyone know who sells a good bearing/seal replacement kit? Ideally the kit would include a bearing puller and a bearing/seal installer. Thanks!

    Hello RDspaguy, I wanted to let you know how my problem ended. You were very helpful to me. I did not replace the breaker. And guess what? The hot tub no longer trips the breaker. My only possible conclusion is that when I disconnected and reconnected everything, something wire that was...

    Which wheels should spin?

    Thank you so much. It’s very helpful to have the manual. Do you know which wheels should be spinning? I see that the manual tells you to count the single wheel rotations. But should the other wheels also be spinning when it is off the pool floor?

    Good morning, This is where I am. I have finished "testing" by disconnecting everything from the control board (except the circulation pump) and separately and independently running the heater, pump 1, pump 2, the blower and the ozonater. I ran each independently for several days. The fuse...

    Parts List for 2011 Sundance Optima 880 Spa

    I am still "testing" the spa by running the circulating Pump and Pump 1 together (without the heater connected). Pump 1 is a jet pump that turns off automatically after 15 minutes or so. Do you know of a way to keep that jet pump running? I want to run it for a long time to see if the breaker...

    Thank you. Today I disconnected the heater and connected Pump 1. (I still have not connected Pump 2 or the Blower). Notably, the breaker immediately tripped (5 straight times). On the 6th try the breaker held. I have the jets running (I think they are controlled by that pump) and I will see...

    OK so I have run it for four days with the heater on and the breaker is not tripped. Should I connect the jet pump? And should I disconnect the heater before I hook up the jet pump? Thanks for your help.

    Thank you for your great help. I will disconnect “everything” this morning. One question, when I disconnect and reconnect, should I disconnect and reconnect the high voltage side of the transformer (and forget about disconnecting and reconnecting the low voltage side)?

    Ok, the breaker blew again. So I disconnected the Ozonator. After about a day, the breaker blew again. So I re-connected the Ozonator and disconnected the heater. I could not reset the breaker with the heater disconnected. (Sometimes the breaker trips on start up and sometimes it trips after...

    Thanks again for your help. To answer your questions: 1) The temperature sensor was unplugged for two days. The heat had most definitely stopped, but the the circulation pump and the jets would operate. (The breaker did not trip during the time that the temperature sensor was unplugged)...
